Upstairs Downstairs

Upstairs Downstairs, the eleventh level of the game, is a two floor map. With large groups of enemies spawning at the bottom that are given the choice to head for the lower rift or to try running up the stairs to the top one. The two new enemies are Ogre variants, the Frost Ogre and Fire Ogre.

There are 40 Rift Points, 12 Waves

Barricades and Archer Guardians are going to be your best friend during this level. Start by blocking off the bottom rift. 3 Barricades on either side will make it so no enemies can get through. This will everyone to try to reach the top rift. Once you have it blocked off place wall or land based traps along the path of the enemies. Keep the traps fairly close to the spawn area as most of your defenses should be down there. After a few waves you should have a decent number off wall traps up and you should now use your money on Archer Guardians. Place them behind your Barricades so that they can fire at the enemy as they spawn. This works surprisingly well and will help clear out large chunks of each wave.

Once you have the Archer Guardians in place, continue placing traps infront of the enemy spawn locations. A couple rows of Brimstone work well to clear our the weaker groups of enemies and Spikes and wall traps will help clear out the rest. Tar and Frost vents can also be placed to give your Archer Guardians more time to fire at the enemy and Spore Mushrooms can be used near the stairs to garuntee no enemy gets through.

The two new enemies you will face are ogre variants. One if the Frost Ogre who is resistant to ice, the other being the Fire Ogre who is resistant to fire. Both of these will be rather easy for you to kill. The Frost Ogre can't be frozen with the Ice Amulet, but your Brimstone will do a lot of damage to him and the Archer Guardians with fire arrows will really help cut him down. You can also charm him with the Sorceress and easily remove him from battle. Fire Ogres are much easier. Since they can be frozen simply blast them with the Ice Amulet a few times and they will drop before they even know what hits them.
